Description

Some futex functions in futex.c for Linux kernel 2.6.x perform get_user calls while holding the mmap_sem semaphore, which could allow local users to cause a deadlock condition in do_page_fault by triggering get_user faults while another thread is executing mmap or other functions.

Affected products

Linux kernel: 2.5.0, 2.5.1, 2.5.2, 2.5.3, 2.5.4, 2.5.5 (+101)
